We prove that the local Euler class of a line on a degree hypersurface in projective space is given by a product of indices of Segre involutions. Segre involutions and…

Felipe Espreafico
In mirror symmetry, after the work by J. Walcher, the number of holomorphic disks with boundary on the real quintic lagrangian in a general quintic threefold is related to the peri…
